Question

Are these the possiable rational zeros for this problem?
f(x)=7x^3-5x^2-63x+45

3,-3, and 5/7?

Answer 1

Didn't we just do this one?

Answer 2

these answers are correct,right

Answer 3

Estudiar not this one, one like it

Answer 4

OK, same answers though...

Answer 5

Jhony-I am pretty sure there wrong, I just put them into my hmwk and it wasnt right

Answer 6

The Wolfram link I gave says they are correct.

Answer 7

yeah maybe I am entering in somthing wrong

Answer 8

for how you have wrote it here these are right sure

Answer 9

The correct answers are 1,-1,3,-3,-18,2,-2,6,-6,9,-9

idk how they got these numbers on my math program

Answer 10

Now its asking for the solution set?

Answer 11

The correct answers are 1,-1,3,-3,-18,2,-2,6,-6,9,-9

Ah, I see, they want POSSIBLE zeros, presumably using the rational roots theorem.

Answer 12

The actual solutions (three of them) are the solution set, same as last time.

That other string of numbers is possible roots that you can work out using the rational roots theorem before you actually know what the roots are...

Answer 13

I put this in as the solution set and it said wrong 3,-3, and 5/7?

hmmm

Answer 14

{3,-3,5/7} (with the curly brackets) is the solution set of the equation in your question.
